WEIGHING-SCALES FOR MAIL-MATTER.

SPECIFICATION forming part of Letters Patent No. 250,413, dated December6, 1881.

Application tiled July 7, 1880. Renewed July 25, 1881. (No model.)Patented n France May 1, 1880, in Germany May 3, 1880, in Great Britainand Ireland May 24, 1880, in Austria May 28, 1880, and iu Belgium May31, 1880.

To all whom it may concern:

Be it known that I, MAURITS J. ALBRACHT, Jr., of Amsterdam, in theKingdom of the Netherlands, have invented a new and useful Improvementin Scales, of which the following is a specification.

The nature of my invention consists of' a balance-scale with acounter-weight, and arranged t-o indicate the weight of letters andpost-packets for inland, as well as the postage of letters, patterns,printings, and book postpapers in accordance with the tariff ot' theInternationalPost Union,bymeansofaparticular arrangement ot' the scalefor every desired weight. This letter-balance forms, therefore, thecombination ot' a post-tariff with a liandbalance. In consequence of aparticular disposition of the lever arrangement and indicator-hand, thegraduated arc or scale will be very convenient i'or the observer toread, and while the bar or post carrying the whole lever arrangement issituated in the center of the scale, the scale extends equally to theright and left hand from said bar or post.

In the accompanying drawings, Figurel represents a front view orelevation ot' my improved scale. is a top view ofthe same. Fig. 3 is aseparate top view of the lever d, and Fig. 4 is a side elevation withthe foot or stand removed.

Similar letters represent similar parts in all the iigures.

F represents the foot or stand, made of any desired shape, andsupporting the central bar or post, a, to which the scale B and thelever arrangement are attached.

bis a cup or plate attached to the rod b', which forms, with the leversd and c and the bar a, a parallelogram, the fulcrums of which are nepoints in the rods b and bar a.. The levers c and d are double, and areconnected together by means of suitable bolts and distancepieces, n af,so that the position ot both paris in relation to each other will remainunchangeable. These levers adjust automatically on the pointedfpinconnections, so that no friction can take place against the sides of therod b and bar c. The upper lever, d, is eX- tended over the bar a, andhas near its end a cross-piece, e, (see Fig. 4,) attached, from whichtwo rods, e e', extend downward, carrying the counter-weights f j" attheir extremities. One

of these rods c c moves at the front ofthe scale B and the other at theback of the same.

For the exact adjustment ofthe balance with the scale or index plate B,the angle formed by the double lever d and rods e c' may be al tered atthe point dthat is to say, the position ot' the counter-weights inrelation to that of the remaining levers and rods may be regulated asrequired.

To the front counter-weight rod, c, an arm, g, is attached, for thepurpose ot' arranging the index-scale B symmetrically to the centralrodor bar, c. lAt the end of the arm g the lever or pointer P isattached, situated in a radial line upon the scale B. This scale-plate Bhas a weight-scale, w, marked on its face, indicating the weights inounces and parts of ounces. Below this there is a scale, o, indicatingthe posta ge'of letters within the International Post Union according tothe Weights determined in the tariff. A similar scale, c', indicates thepostagefor printed matter and book post-papers, anda scale, o, formerchandise, dto., within the International Post Union. Above theweight-.scale w there are three similar scales, s s s", for indicatingthe postage of letters, printing matter, and merchandise within thePostal District of the Inland.

Nhat I claim as my invention, and desire to secure by Letters Patent, is

1. In combination with the parallelogram formed by the levers d c androds b and a, and supporting the disk or plate b, the rods c e',adjustable at d', the arm g, attached to the rod e, with itshand orpointer P attached thereto and placed radially on the graduated arc orscale B, and the Weight to, arranged to operate with a graduated scale,B, substantially in the manner and for the purpose described. z

2. A graduated scale situated symmetrically to both sides of the centralvertical bar, a, and divided to indicate the postage for letters,printed matter, and merchandise within the International Postal Union,as well as for the Postal District ot the Inland, in combination with asuitable hand or pointer, P, substantially in the manner and for thepurpose herein set forth.
